SteamCMD
The Steam Console Client or SteamCMD is a command-line version of the Steam client. Its primary use is to install and update various dedicated servers available on Steam using a command-line interface. It works with games that use the SteamPipe content system. All games have been migrated from the deprecated HLDSUpdateTool to SteamCMD.

Downloading SteamCMD
Windows
1. Create a folder for SteamCMD.
For example:
D:\steamcmd
2. Download SteamCMD for Windows: [1]
3. Extract the contents of the zip to the folder.
Linux
Create a user account named steam to run SteamCMD safely, isolating it from the rest of the operating system.

steamcmd
while operating as the root user. Doing so is a security risk.1. As the root user, create the steam user:
sudo useradd -m steam sudo passwd steam
2. Go into its home folder:
sudo -u steam -s cd /home/steam
Package From Repositories
1. It's recommended to install the SteamCMD package from your distribution repositories, if available:
Ubuntu/Debian:
sudo apt install steamcmd

Dont forget to update, if you add multiverse before installing.
sudo add-apt-repository multiverse sudo apt install software-properties-common sudo dpkg --add-architecture i386 sudo apt update sudo apt install lib32gcc-s1 steamcmd

Change your /etc/apt/sources.list file to contain the following (https://wiki.debian.org/SourcesList#Example_sources.list)
deb http://deb.debian.org/debian bullseye main contrib non-free deb-src http://deb.debian.org/debian bullseye main contrib non-free deb http://deb.debian.org/debian-security/ bullseye-security main contrib non-free deb-src http://deb.debian.org/debian-security/ bullseye-security main contrib non-free deb http://deb.debian.org/debian bullseye-updates main contrib non-free deb-src http://deb.debian.org/debian bullseye-updates main contrib non-free
Now you can update your repositories and install steamcmd
sudo apt install software-properties-common sudo dpkg --add-architecture i386 sudo apt update sudo apt install lib32gcc-s1 steamcmd
RedHat/CentOS:
yum install steamcmd
Arch Linux:
git clone https://aur.archlinux.org/steamcmd.git cd steamcmd makepkg -si

sudo pacman -Syy base-devel
Gentoo:
emerge --ask games-server/steamcmd
2. Link the steamcmd
executable:
sudo ln -s /usr/games/steamcmd /home/steam/steamcmd
Docker
If your server is running Docker, you can simply use:
docker run -it --name=steamcmd cm2network/steamcmd bash
steamcmd.sh
is located at /home/steam/steamcmd
.
This image can be used as a base image for Steam-based dedicated servers. Example: [2]
You can find the associated Docker Hub page here: [3]
Manually
1. Before you begin, you must first install the dependencies required to run SteamCMD:
Ubuntu/Debian (x86-64)
sudo apt-get install lib32gcc-s1
RedHat/CentOS (x86-64)
yum install glibc.i686 libstdc++.i686
2. As the root user, escalate to the steam user:
su - steam
If you're not logging in as root and you instead use sudo
to perform administration, escalate to the steam user as follows:
sudo -iu steam
3. Create a directory for SteamCMD and switch to it.
mkdir ~/Steam && cd ~/Steam
4. Download and extract SteamCMD for Linux.
curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -
5. Install tmux and/or screen for easy server management.
sudo apt-get install tmux screen -y;
macOS
1. Open Terminal.app and create a directory for SteamCMD.
mkdir ~/Steam && cd ~/Steam
2. Download and extract SteamCMD for macOS.
curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_osx.tar.gz" | tar zxvf -
Running SteamCMD
On first run, SteamCMD will automatically update and enter you into a Steam>
prompt. Type help
for more information.
Windows
Open a Command Prompt and start SteamCMD.
cd C:\steamcmd steamcmd
Linux/macOS
Open a terminal and start SteamCMD.
If you installed it using the package from repositories:
cd ~ steamcmd
If you installed it manually:
cd ~/Steam ./steamcmd.sh
SteamCMD Login
Anonymous
To download most game servers, you can login anonymously.
login anonymous
With a Steam Account
Some servers require you to login with a Steam Account.


login <username>
Next enter your password.
If Steam Guard is activated on the user account, check your e-mail for a Steam Guard access code and enter it. This is only required the first time you log in (as well as when you delete the files where SteamCMD stores the login information).
You should see a message stating that you have successfully logged in with your account.
Downloading an App
1. Start SteamCMD, don't login just yet.
2. Set your app install directory. (Note: use forward slashes for Linux/macOS and backslashes for Windows.)
force_install_dir <path>
e.g. a directory named cs_go
inside the current directory:
force_install_dir ./cs_go/
For Windows: force_install_dir c:\cs_go\

.
as a directory. A workaround for this is to use the absolute path to the current directory.3. Login with the login
command
Valve recommends that you set the install dir before logging in.
4. Install or update the app using the app_update
command (supplying a Steam Application ID). Please check here for the dedicated server list: Dedicated server list. To also validate the app, add validate
to the command. To download a beta branch, use the -beta <betaname>
option – for example, the HLDS beta branch is named beta
and the SrcDS beta branch is named prerelease
. Some beta branches are protected by a password; to be able to download from them, also add the -betapassword <password>
option.
app_update <app_id> [-beta <betaname>] [-betapassword <password>] [validate]
HLDS is a special case: the App ID is always 90 and a mod must be chosen first. This is done by setting the app config option mod
to the requested value.
app_set_config <app_id> <option_name> <option_value>
- Example: Install and validate the Counter Strike: Global Offensive dedicated server:
app_update 740 validate
- Example: Install and validate HLDS with Team Fortress Classic:
app_set_config 90 mod tfc app_update 90 validate

app_update
command before all the required files are successfully installed. Simply run app_update 90 validate
multiple times until no more updates take place.- Example: Install and validate beta version of HLDS (Half-Life):
app_update 90 -beta beta validate
- Example: install and validate beta version of the Counter Strike: Source dedicated server:
app_update 232330 -beta prerelease validate
- Example: install and validate a private beta version of the Natural Selection 2 dedicated server (name
alpha
, passwordnatsel
): - [beta name] is the name of the private beta branch
- [beta code] is the password for the private beta branch
app_update 4940 -beta alpha -betapassword natsel validate
The beta name for the non-beta branch is "public", so app_update 90 -beta public will take you off of the beta branch for HLDS.
5. Once finished, type quit
to properly log off of the Steam servers.
quit
Validate
validate
Validate is a command that will check all the server files to make sure they match the SteamCMD files. This command is useful if you think that files may be missing or corrupted.

mapcycle.txt
, this file will be overwritten to the server default. Any files that are not part of the default installation will not be affected.
It is recommended you use this command only on initial installation and if there are server issues.
Supported Servers
A list of known servers that use SteamCMD to install is available on the Dedicated Servers List page. Note that any extra commands listed need to be executed before the app_update line.
Automating SteamCMD
There are two ways to automate SteamCMD. (Replace steamcmd
with ./steamcmd.sh
on Linux/macOS.)
Command Line

-beta
option on the command line, it must be quoted in a special way, such as +app_update "90 -beta beta"
.

"+app_update 90 -beta beta"
instead.
Append the commands to the command line prefixed with plus characters, e.g.:
steamcmd +force_install_dir ../csgo_ds +login anonymous +app_update 740 +quit
To install a specific game mod for HL1, such as Counter-Strike: Condition Zero:
steamcmd +force_install_dir ../czero +login anonymous +app_set_config 90 mod czero +app_update 90 +quit
For a game that requires logins, like Killing Floor:
steamcmd +force_install_dir c:\KFServer\ +login <username> <password> +app_update 215350 +quit
Creating a Script
1. Put your SteamCMD commands in a text file. (You may add comments which start with //
.) Example:
// update_csgo_ds.txt
//
@ShutdownOnFailedCommand 1 //set to 0 if updating multiple servers at once
@NoPromptForPassword 1
force_install_dir ../csgo_ds
login <username> <password>
//for servers which don't need a login
//login anonymous
app_update 740 validate
quit
2. Run SteamCMD with the +runscript
option, referring to the file you created previously. Example:
steamcmd +runscript update_csgo_ds.txt

Failed to load script file 'scriptname.txt'
, try providing an absolute path like /mnt/storage/tf2server/updatetf2_script.txt
Cross-Platform Installation
It is possible to choose the platform for which SteamCMD should download files, even if it isn't the platform it is currently running on. This is done using the @sSteamCmdForcePlatformType
variable. (Yes, those are two "s"es at the beginning of the variable name.) For example, to download the Windows CSGO dedicated server on Linux, you can run the following command:
./steamcmd.sh [email protected] windows +force_install_dir ../csgo_ds +login anonymous +app_update 740 validate +quit
or use the following script:
@ShutdownOnFailedCommand 1
@NoPromptForPassword 1
@sSteamCmdForcePlatformType windows
force_install_dir ../csgo_ds
login anonymous
app_update 740 validate
quit
The supported values are windows
, macos
and linux
.

SteamCMD Guardian 1.2
The following script was tested on Debian Wheezy.
View and download here: http://pastebin.com/hcpMpmaZ
Installation
To make this script work, we need a location. Preferably, you've created a user (e.g., steam) with its own home directory (/home/steam) and are logged in as it via SSH/tty or using su.
- Make the file.
nano updateserver.sh
- Paste in the code
- Modify the code, add at least 1 game to the
DL_SV*=
rows. - Close the file with Ctrl+O, followed by ↵ Enter and concluding with Ctrl+X.
- Give the file execute rights for the user
chmod u+x ./updateserver.sh
- Run the file
./updateserver.sh
The file will auto-download SteamCMD, update it and install all chosen games (up to 4). Run the file again to update the games.

Known Issues
ERROR! Failed to install app "xxxxxx" (No subscription)
If you get the "No subscription" error, the game/server you are trying to download either requires a login or that you have purchased the game. You will therefore have to log in with a Steam username and password. If that doesn't help, you may need to purchase a copy of the game on Steam first. See Dedicated Servers List.


force_install_dir
before logon!For example:
steamcmd +login <username> <password>
32-Bit Libraries on 64-Bit Linux Systems
Since SteamCMD is a 32-bit binary, 32-bit libraries are required.
The following error may occur:
steamcmd: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
The resolution depends on your distro:
Debian-Based Distributions (Ubuntu, Mint, etc.)
sudo apt-get install lib32stdc++6

ia32-libs
are not required to install SteamCMD; lib32gcc1
is enough.
With Debian 7 "Wheezy" you may encounter this error:
The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-multiarch but it is not installable E: Unable to correct problems, you have held broken packages.
To fix this, do the following:
dpkg --add-architecture i386
apt-get update
apt-get install lib32gcc1
Red Hat-Based Distributions (RHEL, Fedora, CentOS, etc.)
yum install glibc.i686 libstdc++.i686
Arch Linux
Don't forget to first enable the multilib repository.
pacman -S lib32-gcc-libs
Login Failure: No Connection
On Linux servers, you may experience a "Login Failure: No Connection" error. This is related to missing iptables rules. You will want something along these lines:
iptables -A INPUT -p udp -m udp --sport 27000:27030 --dport 1025:65355 -j ACCEPT
iptables -A INPUT -p udp -m udp --sport 4380 --dport 1025:65355 -j ACCEPT
The port list is found here: https://support.steampowered.com/kb_article.php?ref=8571-GLVN-8711&l=english
On Windows servers, you may experience "SteamUpdater: Error: Download failed: http error 0" and "SteamUpdater: Error: Steam needs to be online to update. Please confirm your network connection and try again.". This is usually fixed by checking "Automatically detect settings" in IE (Internet Explorer) through the lan settings in the Internet option menu.
- Open Internet Explorer (IE).
- Click on Tools → Internet Options
- Click on the Connections tab
- At the bottom, you should see Local Area Network (LAN) Settings.
- Check the first box (Automatically detect settings)
- Hit OK, and Apply. Try running the SteamCMD again; if it still doesn't work. try lowering your Internet Security level zone to medium or lower. You can find that in the Security tab in Internet Options.
SteamCMD Startup Errors
Unable to Locate a Running Instance of Steam
You may get the following error when starting a server with Linux:
[S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.dll.
Resolve the issue by linking steamclient.so
to the ~/.steam/sdk32/steamclient.so
directory:
ln -s steamcmd/linux32/steamclient.so ~/.steam/sdk32/steamclient.so
ulimit
Linux Startup Error
Some users may get a ulimit
error (no permission/cannot open file) while script is starting up. This error caused by a low setting of the -n
parameter (number of file descriptors) of ulimit
. SteamCMD uses standard commands inside of the initialization shell script to change the ulimit
automatically, but some servers may forbid increasing ulimit
values after startup (or beyond a limit set by root
).
This can be fixed by changing the file descriptor number ulimit:
ulimit -n 2048
If an error appears (no permission), you will have to log in as root to change the parameter. To check the current setting, type ulimit -a; the system will reply with many rows, you need to find one:
open files (-n) 1024
In this case, 1024 is the current value.
root
can also modify the limits in the /etc/security/limits.conf
file.
In most instances you will simply get a warning message however it will not stop SteamCMD from running.
Getting a Linux 64-Bit steamclient.so
on a Windows Machine
WSL does not play nicely with 32-bit files. If you need the steamclient.so 64-bit file you can simply run the following command:
steamcmd.exe [email protected] linux +login anonymous +app_update 1007 +quit
You will then find the file here:
.\steamapps\common\Steamworks SDK Redist\linux64
Only the HLDS Engine is Downloaded
When trying to download a GoldSrc mod like TFC, initially it only downloads the engine files of the HLDS, but not the mod. This happens with both the regular version and the beta. You may have to try multiple times until all the required files are downloaded, but once this is done, the files should update correctly next time.
Work-around for this issue here: http://danielgibbs.co.uk/2017/10/hlds-steamcmd-workaround-appid-90-part-ii/
Just deleting the appmanifest files, without downloading replacements from a third party, may work as well! You will get an error at first though, complaining that something went wrong, which is due to the deleted files.
